Introducing our newest Heavy Duty Flywheel Rotor For Ski-Doo 600 800 1000cc Snowmobiles.
Anyone who rides or repairs the Ski-Doo 600 800 1000cc Snowmobiles is probably familiar with the flywheel problems common to these models. Most of these bikes will have at least one flywheel failure in their lifetime so far. Low quality epoxy was used on OEM flywheels to secure the magnets to the rotor body. Over time and many heat cycles, the epoxy fails allowing the magnets to come loose and contact the stator, potentially causing catastrophic damage.
For years, service shops & dealerships have offered low cost repairs for Ski-Doo flywheels to save the 400$+ OEM replacement. This sounds like a great idea at first, but there are some serious issues!
The common repair is using JB Weld© Marine Blue Epoxy to reattach the loose original magnets, or to install new ones. Epoxy fixes do repair flywheels in short term, if they are done correctly. However, this kind of repair can easily cause immediate problems, and impact long term reliability of your Snowmobile.
A Heavy Duty Flywheel to the rescue!
New RMSTATOR heavy-duty flywheel rotor for Ski-Doo Snowmobile is a well-priced solution to problems with the OEM flywheel, and an excellent alternative to all the mechanical troubles you can encounter with a repair.
Features
- Built to OEM size
Fits precisely in your ride: install it and forget it. - Improved epoxy
Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment. - High grade steel capping

Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator. - Precise balancing
Eliminates crankshaft vibrations for longer engine longevity. - Shop with confidence
One year warranty. All products are tested.
Before attempting to start your Ski-Doo flywheel, adjusting the air gap is necessary. Rotate the flywheel so the raised node is lined up with the pick up/pulser coil and adjust as close as possible but no less than 0.010″.
